Method for a high-speed writing system and high -speed writing device

ABSTRACT

The invention concerns a high speed writing system and a high speed writing device with special menu selection for entering text by means of a pen and a touch-screen. This method of entering text is suitable for desktop PCs, laptop PCs, palmtop PCs, mobile phones (for SMS, WAP and e-mail), watches and other electronic devices. Significantly higher writing efficiency than on a QWERTY keyboard is reached with little investment in practicing time.  
     The monitor screen features a key section with all consonants of the alphabet, as well as one vowel key distinguished by its arrangement and function. All elements of the writing process defining the method can be generated by pen movements such as selection of a key or guiding it in one of eight stroke directions, as well as combinations of these pen movements  
     The high speed writing devices described here excel by their small and ergonomically arranged entry sections, whereby all keys for text entry can be reached from one single hand position that never needs re-setting.

[0001] The present invention describes a method for a high speed writing system with menu selection by pen and touch screen per claim 1 and a high speed writing device for implementation of this method per claim 22.

[0002] Miniaturization of electronic equipment continues making great progress and offers new mobile solutions such as SMS (Short Message System) und WAP (Wireless Application Protocol). The advantages offered by this development are, however, accompanied by drawbacks such as lack of ergonomy and small, poorly arranged screens. One crucial and continuing problem is the entering of text.

[0003] Recognition of spoken language is already more advanced than recognition of handwritten text. Nevertheless, a silent form of entering text is preferable over the oral form, for respecting privacy and confidentiality e.g. in public transportation, in public places and open-plan offices.

[0004] The most popular method for entering text is by keyboard, first of all the QWERTY keyboard. Keyboards are designed for typing using the fingers. This is the main reason why the size is a minimum of appx. 24×8 cm if entering by the 10 finger system is a requirement. There is also equipment with significantly smaller QWERTY keyboards precluding practical use of the 10 finger system. This does not really make sense as better and clearer keyboard layouts exist where far shorter distances must be travelled by a single finger.

[0005] Despite the fact that more efficient and simpler to learn keyboard layouts exist, the QWERTY keyboard has become the standard (M. Helander (ed.), Handbook of Human-Computer Interaction, Elsevier (1988), pp. 475-479).

[0006] Miniature QWERTY keyboards which are equally as large and voluminous as the portable phone itself are optionally available for mobile telephony (SMS). Supplementary full size keyboards (whereby one product can be folded up) are available for palm top applications with touch screen. Keyboards of this kind are about four times the volume of the palm top set itself. An approach, as described in these examples, is opposing the idea of miniaturization and indicates the need for equipment with new methodes of entering text.

[0007] The figure keys of cellular phone keyboards are additionally occupied by three letters. One of the three letters is entered by several brief actuations of the key at short intervals. This form of entering text is reasonably space-saving but very tedious and slow. Enthusiatic SMS writers exhibit amazing readiness to achieve perfection in this form of entering data.

[0008] A very similar improved device (Nokia Mobile Phones Ltd., Salo, Finnland) demands touching of the keys only once although each key has multiple functions. By use of a stored vocabulary the device recognizes the word being typed. If a word to be entered is not stored in the vocabulary and if the device identifies several possible words the writer must choose the desired word from a menu. This step detracts from the actual writing process, or even interrupts it, if the menu does not display the desired word.

[0009] One approach to improving entering of text is by using so called touch screen monitors; because they serve the double purposes of entering and monitoring. The available area is thus put to optimum use. Devices with a touch screen monitor without keyboard represent, therefore, an interesting alternative.

[0010] There are such devices which display an on-screen keyboard (most commonly QWERTY), where individual key sections are tapped by a pen. Basically they work the same way as the palm top applications already described (PSION Computers PLC), with an actual keyboard. Even if the keyboard has been optimized for pen use (single finger system), every single character needs a “key”displayed, calling for additional screen area. Furthermore, every character must be tapped individually causing a lot of pen movement while increasing error tendency at the same time.

[0011] Several touch screen devices offer hand writing recognition. Unfortunately this feature does not work optimally. There are systems that try to anticipate entire words using extensive vocabulary. Handwriting is very frequently erroneously interpreted by the device, causing the user to be diverted from the actual writing process. There is an other system which requires entering every single letter in handwriting (capital lettering) which is quite slow. Letters need to be entered by a special ‘Graffiti’-alphabet (U.S. Robotics, Palm Computing Division, Los Altos, Calif. U.S.A.). Frequent use of the Graffiti alphabet may cause alterations to the personal hand writing style. An additional problem of these devices is their demanding programming which calls for memory space and processing capacity and entails delayed display of the text entered.

[0012] When writing on paper a support is necessary and the hand must be guided which is especially cumbersome under limited space conditions. When using standard hand writing (longhand) a large number of movements must be carried out by the hand. An abbreviated writing method such as shorthand according to Stolze/Schrey (Emil Hug), Englische Stenographie, 16th. edition 1960) enables faster writing. In exchange, new characters, abbreviations of words and a shortened, orthographically incorrect, way of writing must be learnt. An equally high learning effort is required for fluent reading of shorthand.

[0013] Under U.S. Pat. No. 6,008,799 a writing system has been described that employs a touch screen. All characters and the most frequent words are shown as keys, resulting in a total of 92 keys. The keys are arranged in alphabetical order which has proved inferior to an arrangement based on frequency of use. (M. Helander (ed.), Handbook of Human-Computer Interaction, Elsevier (1988), p. 479). In addition, a vocabulary listing is also displayed. On a monitor, an area of approximately 12'20 cm is taken up, seriously limiting applications in the desk top and lap top range. As a supplement of the keys, vowels can also be entered with so-called ‘flicks’ or straight lines going in different directions. A great disadvantage is that only four flicks are provided (left, right, up or down). As a consequence the letter ‘U’ cannot be entered by a flick. Clear systematics are thus not possible. The high number of keys renders the layout cluttered and, therefore, hard to memorize. In order to actuate the proper keys the user must travel long distances with the pen which is very time-consuming. Depending on the case, the vocabulary window may need scrolling. This requires additional attention and detracts from the actual writing process. There is no provision for chaining flicks up, or inputting them in continuous sequence.

[0014] The objective of the invention is to present a method for a high speed writing system which circumvents the mentioned disadvantages.

[0015] It is another objective to describe a high speed writing device with menu selection by pen and touch screen for implementing the method. Such device is also very suitable for mobile applications.

[0016] The problem is solved by a method per claim 1 and a high speed writing device per claim 22.

[0017] The method and the associated high speed writing device will be described below. The illustrations show:

[0040] In the present invention the following terms are defined:

[0041] 1. Basic Moves as a first set of pen movements of the basic kind:

[0042] Tap: Setting down and lifting the pen at the same location

[0043] Stroke: Setting down, simple or composite pen movements (without stopping) in one of the eight stroke directions and lifting the pen off

[0044] Shortcut of the 1^(st) kind: Setting down on a key, pen movement in one of the three ‘UP’ directions and lifting the pen off

[0045] Shortcut of the 2^(nd) kind: Setting down on a key, pen movement in one of the three ‘UP’ directions, pen movement in one of the eight stroke directions and lifting the pen off

[0046] Double Tap: Setting down, lifting off,and setting down again on the same key (within a short time interval) and lifting the pen, or Setting down, lifting off, and setting down again on the same key (within a short time interval), carrying out any kind of pen movement and lifting the pen off.

[0047] 2. Double Tap Shortcut as a second set of pen movements of a combined nature: They always start by Double Tap from the vowel field or vowel key; respectively, after which always any one key is chosen, i.e.:

[0048] Double Tap on vowel key, Double Tap on any one key, or

[0049] Double Tap on vowel key, Tap on any one key, or

[0050] Double Tap on vowel key, stroke on any one key

[0051] 3. Nine-square window of the 1^(st) kind: a menu window for selection. One word, letter or sequence of characters or symbols is in the center, all remaining eight are arranged in a circle around the center.

[0052] 4. Nine-square window of the 2^(nd) kind: a menu window for selection; it appears, triggered by a choice in the nine-square window of the 1^(st) kind. One word, letter or sequence of characters or symbols is in the center, all remaining eight are arranged in a circle around the center

[0053] 5. Quad-square window: a menu window for selection. A word, a letter or symbol is located in the center; the remaining three are arranged above it.

[0054] 6. Five-square window: a menu window for selection. A word, a letter or symbol is located in the center; the remaining four are arranged above it and one is half covered, below the square in the center.

[0055]FIG. 1 shows a block diagram of a high speed writing device 100. An entering pad 10, a monitor 11, a processor unit 12, a memory 13 and connecting lines 14, 15 are installed in a case (not shown).

[0056] The entering pad 10, located above the monitor 11, is transparent and has a touch-sensitive entering surface provided with an entering section 16 and a text section 17. Together they form a touch screen of the known kind.

[0057] Entering section 16 and text section 17 are relocatable and of variable size. They are arranged on the touch screen in the usual window technique. The text section is located to the left of the entering section in an arrangement preferably for right-handed users.

[0058] Entering element 10 is connected to processor unit 12 by line 14; processor unit 12, in turn, is connected up to memory unit 13.

[0059] Processor unit 12 is, on the other hand, connected to monitor unit 11 (e.g. a LCD screen) by line 15, across which all informations are forwarded for image generation in text display section 17.

[0060] An entry module 18 is located in processor unit 12 which is connected by another line, line 19, to processing module 20. The internal code is transferred to the processing module via line 19.

[0061] Entering section 16 is callable and variable in size. A variable key pad 21, also variable in size, is an integral part of the entering section. This key pad is sub-divided into single keys, consonant keys 22 and a vowel key 25. An entry, such as a character, is triggered by hand guided pen 23, selecting one of the keys 22, 25.

[0062] Furthermore, pen movements in eight selected, or preferred, stroke directions 1, 2, . . . , 8 whose functions will be gone into later on.

[0063] The x/y coordinates of the contact point of pen and touch screen are forwarded to processor unit 12 via line 14. Lines 14 and 15, as well as line 19, may also be configured as bi-directional lines.

[0064] The characters generated are displayed in text section 17. In the absence of a text section they are directly processed in processor unit 12 and stored in memory 13. Text section 17 may be missing if tight space conditions do not allow for it, e.g. if the high speed writing device is integrated in a watch, as an example of execution, as described later.

[0065] Pen 23 has a rounded tip and does not permit actual writing. It serves the purpose of selecting keys, or of calling up sections on the touch screen, and of carrying out pen movements.

[0066] A software implemented in processor unit 12 is required for all processing of the entries carried out by the pen in the key section.

[0067]FIG. 2 represents an entry pad with a key section featuring one of the possible frequency distributions of consonants for the English language.

[0068] Entry section 16 is sub-divided into 6×7, usually square-shaped, cells, 4×5 of which define key section 21, whereby the key section is centered such that a row, or a column, respectively, of free cells is provided.

[0069] Key section 21 is sub-divided into character keys, and T(I,K), respectively, whereby I signifies the rows, and K signifies the columns of the key section. Key T(3,3) is a so-called vowel key 25 the function of which shall be described later. The consonants have been assigned keys T(1,1) to T(5,4) in such a manner as, to arrange frequently used consonants centrally and less frequently, or rarely, used consonants mainly at the periphery. As an example, rare consonants W and Z are located on keys T(1,1) and T(5,4). The arrangement shown here is one of many possible arrangements taking into account the frequency distribution of consonants. These arrangements are specific to each language.

[0070] Sub-division of the entry section into 6×7 square cells is provided for allocation of the keys to given x/y coordinates. A special key section 24, for special signs, such as punctuation and others, may be located beside key section 6.

[0071]FIG. 3 represents an entry section with a key section featuring one of the possible frequency distributions of consonants for the German language.

[0072] Shown again are key T(3,3) as vowel key 25, surrounded by 19 consonant keys 22. The consonant arrangement again meets the same condition as in FIG. 2, namely to ensure the shortest possible distances to the most frequent consonants.

[0073] The basics of the high speed writing system shall be explained by a first choice of operational directions

[0074] Strokes starting on a consonant key have an influence on that consonant or attach vowels to it.

[0075] When the vowel key is touched, a vowel is written.

[0076] A word must be completed by a ‘left-up’ stroke (space).

[0077] For any combination of lines, the start key only is of importance. Keys that will be crossed over along the way have no bearing.

[0078] Tap () writes the selected consonant singly and without alteration.

[0079] A word started by a ‘left-up’ stroke is written in capital letters.

[0080] ‘Tap’ and ‘Stroke’, both of them belonging to the ‘Basic Moves’, will generate letters or letter sequences, i.e. syllables, respectively, as illustrated by the following simple examples:

[0081] Setting the pen down on a consonant key and lifting it off again makes the tapped/selected consonant appear on the screen. This is an input acknowledgement since the entry can be verified in the text section. This acknowledgement is not a necessity, however. It is essential that the input be processed by the processor provided, then stored in memory.

[0082] Setting the pen down on the vowel key, then carrying out a pen stroke in one of the stroke directions for vowels A, . . . , U then lifting it off will generate the entry of the tapped/selected vowel.

[0083] Setting the pen down on a consonant key, then carrying out a pen stroke in one of the stroke directions for vowels A, . . . , U then lifting it off will generate the entry of the tapped/selected consonant, followed by the respective vowel.

[0084] Actuating a double tap on a consonant key will double up the corresponding consonant, generate a special symbol, or a word according to the fourth column from the right (FIG. 7).

[0085] Setting the pen down on a consonant key, followed by stroke ‘left-up’ and lifting it off again, will cause the selected consonant to become a capital letter according to the third column from the right (FIG. 7).

[0086] Setting the pen down on a consonant key, followed by stroke ‘up’ and lifting it off again, will generate a letter sequence or a word according to the second column from the right (FIG. 7).

[0087] Setting the pen down on a consonant key, followed by stroke ‘right-up’ and lifting it off again, will generate a letter sequence or a word according to the first column from the right (FIG. 7).

[0088] Setting the pen down on the vowel key, followed by a stroke in one ot the three stroke directions, and lifting it off again, will execute functions such as ‘SPACE’, ‘BACK SPACE’, or‘DELETE’.

[0089] Setting the pen down on the vowel key, followed by Double Tap (shaded square), will start the ‘Double Tap Shortcut’; following this, a Tap, Double Tap, or a pen movement in one of the stroke directions, will be carried out on any one key.

[0090] Executing a Double Tap on the ‘X’ key (shaded square) will cause a menu window to appear with an EXIT key, a figure key and four selectable windows for student tutoring. Selecting the X key is not an absolute necessity. It is of the essence to select a key rarely used which is, no doubt, the case for ‘X’.

[0091] FIGS. 6A-6D show a connected sequence of entries. This shall explain how the sentence ‘he is walking’ appears in the text section.

[0092]FIG. 6A shows entry section 16 and text section 17 beside it, as part of a monitor, or of an entry area. The consonants of the entry section have been arranged around the vowel key according to their frequency of use in the English language.

[0093]FIG. 6B shows entering by the pen starting on H key followed by strokes ‘right-down’, then ‘left-up’. This sequence will generate and display, the word ‘he ’ followed by a space, in the text section.

[0094]FIG. 6C shows the subsequent entry by the pen starting on the vowel key with stroke ‘down’, lifting off, then setting pen down on S with stroke ‘left-up’. This sequence will generate and display the word ‘is’ in the text section.

[0095]FIG. 6D shows the subsequent entry by the pen starting on W key followed by strokes ‘right’, lifting off, then setting pen down on K key with stroke ‘down’, lifting off, then double tap G key, then stroke ‘left-up’. This sequence will generate and display the word ‘walking ’ in the text section.

[0096]FIG. 8 shows a chart with double tap shortcuts. The top line shows the columns below titled ‘Key’, ‘Double Tap’ ‘Tab’ and with eight stroke directions. All pen movements belonging to this chart are carried out starting with Double Tap from the vowel key, followed by:

[0097] a Double Tap on any one key, or

[0098] a Tap on any one key, or

[0099] a Stroke on any one key.

[0100] The words allready filled in may be changed by the user. The gaps, or open locations of this chart are, again at the individual disposal and may be filled in with the most frequent personal words.

[0101] Executing a Double Tap on the bowel key followed by Double Tap on any one key will generate words in accordance with the tenth column from the right (FIG. 8).

[0102] For example, Double Tap on the vowel key followed by Double Tap on C key will generate the word ‘computer_’, followed by a space.

[0103] Executing a Double Tap on the vowel key followed by Tap on any one key will generate the words in accordance with the ninth column from the right (FIG. 8).

[0104] For example, Double Tap on the vowel key followed by Tap on T key will generate the word ‘trough_’.

[0105] Executing a Double Tap on the vowel key followed by a Stroke will generate words in accordance with the first to eight columns from the right (FIG. 8).

[0106] For example, Double Tap on the vowel key followed by stroke ‘left-up’ from Z key will generate the word ‘Zurich_’.

[0107] Or, Double Tap on the vowel key followed by Stroke ‘right’ from the vowel key will generate the word ‘available’.

[0108] It follows that a total of 20*10 words are programmable under the ‘Double Tap shortcuts’ function.

[0109]FIG. 10A shows nine menu windows that belong to the vowel key. They are presented on the monitor one by one, only. They are tutoring programs for as long as the user does not know the various meanings of the eight strokes and of their combinations. The menu windows shown here represent the maximum degree of assistance.

[0110] A nine-square window of the 1^(st) kind is located in the center with eight associated nine-square windows arranged around. The periphery of the nine-square window of the 1^(st) kind consists of eight double-framed keys. Each of the eight nine-square windows of the 2^(nd) kind features a double-framed key in the center.

[0111] Setting the pen down on the vowel key will call for the nine-square window shown here to appear on the monitor. Being centered over the vowel key it covers up the key section. The ENTER key is located in the center of this nine-square window. It is selected by lifting the key off without stroke. Making pen strokes in any one of the eight stroke directions triggers a selection in this menu window of the 1^(st) kind. If, as an example, stroke ‘right-up’ is carried out (selecting double-framed DELETE key) the window with the DELETE key in the center will appear. Being centered over the DELETE key it covers up the key section. Lifting the pen off without stroke will select and execute DELETE. Leaving the pen on the surface and making stroke ‘left’ (select ‘and_’ key) will generate the word ‘and’ followed by a space.

[0112]FIG. 10B shows four menu windows that belong to the vowel key. They are presented on the monitor one by one, only. They are tutoring programs for as long as the user does not know all the various meanings of the eight strokes and of their combinations. The menu windows shown here provide a medium degree of assistance. The user is familiar with the five vowel-generating strokes.

[0113] A five-square window is located in the center with four associated nine-square windows of the 2^(nd) kind arranged above. The shaded, partly covered key symbolizes the access to the double tap shortcuts. Setting the pen down on the vowel key, followed by double tap, will start the ‘double tap shortcut’; following this, a tap, double tap, or a pen movement in one of the stroke directions, will be carried out on any one key. The periphery of the nine-square window consists of eight double-framed keys. Each of the nine-square windows features a double-framed key in the center.

[0114] Setting the pen down on the vowel key will call for the five-square window shown here to appear on the monitor. Being centered over the vowel key it covers up the key section. The ENTER key is located in the center of this five-square window. It is selected by lifting the key off without stroke. Making pen strokes in any one of the three ‘UP’-stroke directions triggers a selection in this menu window of the 1^(st) kind. If, as an example, stroke ‘right-up’ is carried out (selecting double-framed DELETE key) the window with the DELETE key in the center will appear. Being centered over the DELETE key it covers up the key section. Lifting the pen off without stroke will select and execute DELETE. Leaving the pen on the surface and making stroke ‘right’ (select ‘also_’ key) will generate the word ‘also’ followed by a space.

[0115]FIG. 11A shows five menu windows that belong to the P key. They are presented on the monitor one by one, only. They are tutoring programs for as long as the user does not know all the various meanings of the eight strokes and of their combinations. The menu windows shown here provide a medium degree of assistance. The user is familiar with the five vowel-generating strokes.

[0116] A five-square window is located in the center with four associated windows arranged around. The periphery of the five-square window consists of four double-framed keys. Each of the four windows of the 2^(nd) kind features a double-framed key in the center.

[0117] Setting the pen down on the P key will call for the five-square window shown here to appear on the monitor. Being centered over the P key it covers up the key section. The ‘p’ key is located in the center of this five-square window. It is selected by lifting the key off without stroke. Making pen strokes in any one of the three ‘UP’-stroke directions triggers a selection in this menu window of the 1^(st) kind. If, as an example, stroke ‘right-up’ is carried out (selecting double-framed ‘sp’ key) the window with the ‘sp’ key in the center will appear. Being centered over the ‘sp’ key it covers up the key section. Lifting the pen off without stroke will select and generate ‘sp’. Leaving the pen on the surface and making stroke ‘left-down’ (select ‘spo’ key) will generate the letter sequence ‘spo’.

[0118]FIG. 11B shows five menu windows that belong to the P key. They are presented on the monitor one by one, only. They are tutoring programs for as long as the user does not know all the various meanings of the eight strokes and of their combinations. The menu windows shown here provide a minimum degree of assistance. The user is familiar with the five vowel-generating strokes. The user is familiar with the basic meaning of the eight stroke directions

[0119] A five-square window is located in the center with four associated windows arranged around. The periphery of the five-square window consists of four double-framed keys. Each of the four windows of the 2^(nd) kind features a double-framed key in the center.

[0120] Executing a Double Tap, e.g., on the P key will let the four-square window shown here appear on the monitor. Being centered over the P key it covers up the key section. The ‘pp’ key is located in the center of this four-square window It is selected by lifting off the pen without a stroke. Making pen strokes in any one of the three ‘UP’-stroke directions triggers a selection in this menu window of the 1^(st) kind. If, as an example, stroke ‘up’ is carried out (selecting vacant key) the window with the vacant key in the center will appear. Lifting the pen off without stroke will select a word hitherto undefined.

[0121] The letters (or letter sequences) ‘P’, ‘sp’ and ‘pp’ are frequently followed by vowels. For this reason the vowel-generating strokes are not available to generate words from the respective menu windows. In this case the vowel-generating strokes have already been assigned letter combinations such as e.g. ‘spa’, ‘spo’, ‘ppe’ or ‘ppi’.

[0122]FIG. 12 shows five menu windows that belong to the F key. They are presented on the monitor one by one, only. They are tutoring programs for as long as the user does not know all the various meanings of the eight strokes and of their combinations. The menu windows shown here provide a minimum degree of assistance. The user is familiar with the five vowel-generating strokes. The user is familiar with the basic meaning of the eight stroke directions

[0123] A five-square window is located in the center with four associated windows arranged around. The periphery of the five-square window consists of four double-framed keys. Each of the four windows of the 2^(nd) kind features a double-framed key in the center.

[0124] Setting the pen down on the F key will call for the five-square window shown here to appear on the monitor. Being centered over the F key it covers up the key section. The ‘f’ key is located in the center of this five-square window. It is selected by lifting the key off without stroke. Making pen strokes in any one of the three ‘UP’-stroke directions triggers a selection in this menu window of the 1^(st) kind. If, as an example, stroke ‘up’ is carried out (selecting double-framed ‘first^(—)’ key) the window with the ‘first_’ key in the center will appear. Being centered over the ‘first^(—)’ key it covers up the key section. Lifting the pen off without stroke will select and generate the word ‘first^(—)’. Leaving the pen on the surface and making stroke ‘right-up’ (select ‘after^(—)’ key) will generate the word ‘after’ followed by a space.

[0125] Executing a Double Tap, e.g., on the F key will let the four-square window shown here appear on the monitor. Being centered over the F key it covers up the key section. The ‘ff’ key is located in the center of this four-square window It is selected by lifting off the pen without a stroke. Making pen strokes in any one of the three ‘UP’-stroke directions triggers a selection in this menu window of the 2^(nd) kind. If, as an example, stroke ‘left-up’ is carried out (selecting vacant key) the window with the vacant key in the center will appear. Lifting the pen off without stroke will select a word hitherto undefined.

[0126] The method shall be explained further by means of flow charts in what follows.

[0127]FIG. 13 shows a flow chart for the entry module. In the entry module the keys selected and the pen movements originating therefrom (Tap, Double Tap and Strokes) are identified. A program loop allows the pen to be guided freely while providing identification and sequential combination of the respective vowels and functions.

[0128] The entry module basically analyzes the pen movements and translates them into a standardized internal code. The individual signs of this code are one-place. Pen movements such as Tap, stroke directions, and Double Tap have been assigned numbers 0 to 9. Menu windows selected are assigned the consonant shown on the respective key. Letter ‘A’ has been assigned to the vowel key.

[0129] The internal code consists of 30 control signs. Each control sign identified is immediately forwarded to the processing module where it is inserted in its respective location in the program flow. The processing module ensures correct interpretation of single or combined code signs and generation of the corresponding letter or combination of letters. The following example illustrates how a text entered is translated into internal code:

[0130] Touch_screen^(—)devices_are_ENTER

[0135] The entry module forwards the code to the processing module where it is translated back to the original text.

[0136] This section of the program starts with setting the pen down (Step 1301) whereby the x/y coordinates of the contact point on the entry surface are generated. Step 1302 identifies the key and forwards the pertinent information, i.e. a one-place sign (letter), to the processing module which is also a part of the central processor.

[0137] Step 1303 verifies whether the pen has been lifted off. If the answer is ‘Yes’, step 1304 then carries out verification whether the pen was set down again within 0.3 seconds. If ‘Yes’, control sign ‘9’ is clearly identified and forwarded as information to the processing module (step 1305). Subsequently, step 1306 verifies whether the pen has been lifted off. If ‘Yes’ (a Double Tap has been executed) the program segment ends by ‘Return’ (step 1307), taking the program back to the starting point.

[0138] If the answer in step 1304 was ‘No’ (a Tap has been executed), this signifies control sign ‘0’ which is forwarded as information to the processing module (step 1308), whereupon the program segment ends by ‘Return’ (step 1307); cf. also FIG. 9.

[0139] If the answer in step 1306 is ‘No’, pen movement (step 1309) is carried on. Step 1311 then identifies stroke direction ‘1’, i.e. when the pen is moved ‘right’, this movement is assigned stroke direction ‘1’ and the corresponding information, or the control sign, respectively, is forwarded to the processing module. Continuation is by step 1312. Stroke directions ‘2’ to ‘8’ are similarly identified by steps 1312 to 1318 and the respective informations are then forwarded to the processing module.

[0140] Step 1310 carries out verification whether the pen was lifted off the surface. If ‘Yes’ the program segment ends by ‘Return’ (step 1307), taking the program back to the starting point. If the answer in step 1310 is ‘No’, continuation is by step 1309.

[0141]FIG. 14 shows a flow chart as an outline for the processing module with indications pertaining to related further flow charts.

[0142] Control signs generated in the entry module are read and processed by the processing module. Processing of control signs is started when a control sign is received from the entry module (step 1401).

[0143] Next step, 1402, carries out verification whether the control sign is ‘A’. If ‘Yes’, step 1403 will identify the vowel shortcuts, as described by flow chart in FIG. 16.

[0144] If menu windows are to be displayed, these will be triggered between steps 1402 and 1403. Thus, e.g. a nine-square window (FIG. 10A) or the five-square window (FIG. 10B), will show up in the case where the medium degree of tutoring has been selected.

[0145] Step 1404 then identifies the vowel add-ons as described in flow chart, FIG. 21. The procedure then ends by ‘Return’ (step 1405), whereupon continuation is from ‘Start’.

[0146] If the answer in step 1402 is ‘No’, step 1406 carries out verification whether the control sign is ‘B’. If ‘Yes’, step 1407 will identify the B shortcuts, as illustrated later by the example of the Z-Shortcut. Step 1404 then again identifies the vowel add-ons whereupon the procedure ends by ‘Return’ (step 1405), after which continuation is from ‘Start’.

[0147] If the answer in step 1406 is ‘No’, step 1408 carries out verification whether the control sign is ‘C’. If ‘Yes’, step 1409 will identify the C shortcuts. Step 1404 then again identifies the vowel add-ons whereupon the procedure ends by ‘Return’ (step 1405).

[0148] Checking for control signs ‘D’ to ‘X’ is carried out in analogous fashion by steps 1410 to 1420 whereby the respective consonant shortcuts are identified by steps 1411 to 1421 or 1422 followed by vowel add-ons (step 1404) and ‘Return’ (step 1405).

[0149] If the answer in step 1420 is ‘No’, step 1422 will identify the Z shortcuts as described in flow chart, FIG. 15.

[0150]FIG. 15 shows a flow chart to determine the consonant short cuts, namely the P short cuts. This section of the program starts with step 1501. In step 1501 control sign ‘P’ was identified.

[0151] Control signs generated in the entry module are read and processed by the processing module.

[0152] Next step, 1502, carries out verification whether the control sign is ‘0’. If ‘Yes’, step 1503 will generate the letter ‘p’. Step 1504 then identifies the vowel add-ons.

[0153] If the answer in step 1502 is ‘No’, step 1505 carries out verification whether the control sign is ‘6’. If ‘Yes’, step 1520 will read the next control sign.

[0154] If menu windows are to be displayed, these will be triggered between steps 1505 and 1520. Thus, e.g. a nine-square window (FIG. 10A) or the five-square window (FIG. 10B), will show up in the case where the medium degree of tutoring has been selected.

[0155] Next step, 1506, carries out verification whether the control sign is ‘0’. If ‘Yes’, step 1519 will generate the letter ‘p’ followed by a space. Step 1504 then identifies the vowel add-ons.

[0156] If the answer in step 1506 is ‘No’, step 1507 carries out verification whether the control sign is ‘7’. If ‘Yes’, step 1508 will generate the word ‘up_’ followed by a space. Step 1504 then identifies the vowel add-ons.

[0157] If the answer in step 1507 is ‘No’, step 1509 carries out verification whether the control sign is ‘8’. If ‘Yes’, step 1510 will generate the letter sequence ‘sp’. Step 1504 then identifies the vowel add-ons.

[0158] If the answer in step 1509 is ‘No’, step 1511 will generate the letter ‘P’. Step 1504 then identifies the vowel add-ons.

[0159] If the answer in step 1505 is ‘No’, step 1512 carries out verification whether the control sign is ‘7’. If ‘Yes’, step 1513 will determine the P7 shortcuts of the 2^(nd) kind as described in flow chart, FIG. 18 with the L7 shortcuts of the 2^(nd) kind. Step 1504 then identifies the vowel add-ons.

[0160] If the answer in step 1512 is ‘No’, step 1514 carries out verification whether the control sign is ‘8’. If ‘Yes’, step 1515 will determine the P8 shortcuts of the 2^(nd) kind. Step 1504 then identifies the vowel add-ons.

[0161] If the answer in step 1514 is ‘No’, step 1516 carries out verification whether the control sign is ‘9’. If ‘Yes’, step 1517 will determine the P9 shortcuts of the 2^(nd) kind. Step 1504 then identifies the vowel add-ons.

[0162] If the answer in step 1516 is ‘No’, step 1518 will generate the letter ‘p’. Step 1504 then identifies the vowel add-ons.

[0163] The flow charts of the consonant shortcuts differ in their content only. They are identical in structure.

[0164]FIG. 16 shows a flow chart to determine the vowel shortcuts. This section of the program starts with step 1601. In step 1601 control sign ‘A’ was identified.

[0165] Control signs generated in the entry module are read and processed by the processing module.

[0166] Next step, 1602, carries out verification whether the control sign is ‘0’. If ‘Yes’, step 1603 carries out the function ‘ENTER’. Step 1604 then identifies the vowel add-ons.

[0167] If the answer in step 1602 is ‘No’, step 1605 carries out verification whether the control sign is ‘6’. If ‘Yes’, step 1606 will determine the A6 shortcuts of the 2^(nd) kind as described in FIG. 17. Step 1604 then identifies the vowel add-ons.

[0168] If the answer in step 1605 is ‘No’, step 1607 carries out verification whether the control sign is ‘7’. If ‘Yes’, step 1608 will determine the A7 shortcuts of the 2^(nd) kind as described in FIG. 18. Step 1604 then identifies the vowel add-ons.

[0169] If the answer in step 1607 is ‘No’, step 1609 carries out verification whether the control sign is ‘8’. If ‘Yes’, step 1610 will determine the A8 shortcuts of the 2^(nd) kind. Step 1604 then identifies the vowel add-ons.

[0170] If the answer in step 1609 is ‘No’, step 1611 carries out verification whether the control sign is ‘9’. If ‘Yes’, step 1612 will determine the double tap shortcuts as described in FIG. 19. Step 1604 then identifies the vowel add-ons.

[0171] If the answer in step 1611 is ‘No’, the vowel add-ons are identified (step 1604).

[0172] Menu windows are displayed according to FIG. 10B, similarly as described in FIG. 15

[0173]FIG. 17 shows a flow chart to determine the A6 shortcuts of the 2^(nd) kind. This section of the program starts with step 1701. Step 1701 followes step 1605 (FIG. 16) where control sign ‘6’ was identified.

[0174] Control signs generated in the entry module are read and processed by the processing module.

[0175] Next step, 1702, carries out verification whether the control sign is ‘0’. If ‘Yes’, step 1703 carries out the function ‘SPACE’. Step 1704 then identifies the vowel add-ons.

[0176] If the answer in step 1702 is ‘No’, step 1705 carries out verification whether the control sign is ‘1’. If ‘Yes’, a control sign is read (not shown). Step 1706 carries out verification whether the control sign is ‘7’. If the answer is ‘Yes’, step 1707 will generate the letter sequence ‘Al’. Step 1704 then identifies the vowel add-ons.

[0177] If the answer in step 1706 is ‘No’, step 1708 carries out verification whether the control sign is ‘8’. If ‘Yes’ step 1709 will generate the letter sequence ‘Ar’. Step 1704 then identifies the vowel add-ons.

[0178] If the answer in step 1708 is ‘No’, step 1710 will generate the letter ‘A’ in capital lettering. Step 1704 then identifies the vowel add-ons.

[0179] Checking for control signs ‘2’, ‘3’ to ‘6’ is carried out in analogous fashion whereby the respective letters and letter sequences e.g. ‘J’, ‘Y’, ‘Ol’ and capital lettering are identified. Step 1704 then identifies the vowel add-ons.

[0180] If the answer in step 1711 is ‘No’, step 1712 carries out verification whether the control sign is ‘7. If ‘Yes’ step 1713 will generate the word ‘use_’ followed by a space. Step 1704 then identifies the vowel add-ons.

[0181] If the answer in step 1712 is ‘No’, step 1714 carries out verification whether the control sign is ‘7. If ‘Yes’ step 1715 will generate the word ‘user_’ followed by a space. Step 1704 then identifies the vowel add-ons.

[0182] If the answer in step 1714 is ‘No’, step 1704 identifies the vowel add-ons.

[0183]FIG. 18 shows a flow chart to determine the L7 shortcuts of the 2^(nd) kind. This section of the program starts with step 1801. Step 1801 follows step 1605 (FIG. 16) where control sign ‘7’ was identified.

[0184] Control signs generated in the entry module are read and processed by the processing module.

[0185] Next step, 1802, carries out verification whether the control sign is ‘0’. If ‘Yes’, step 1803 will generate the special sign ‘.’. Step 1804 then identifies the vowel add-ons.

[0186] If the answer in step 1802 is ‘No’, step 1805 carries out verification whether the control sign is ‘1’. If ‘Yes’, step 1806 will generate the special sign ‘)’. Step 1704 then identifies the vowel add-ons.

[0187] If the answer in step 1805 is ‘No’, step 1807 carries out verification whether the control sign is ‘2’. If ‘Yes’, step 1810 will generate the special sign ‘:’. Step 1704 then identifies the vowel add-ons.

[0188] Checking for control signs ‘3’, ‘4’ to ‘7’ is carried out in analogous fashion whereby the respective special signs are generated.

[0189] If the answer in step 1809 is ‘No’, step 1810 carries out verification whether the control sign is ‘8’. If ‘Yes’, step 1811 will generate the special sign ‘!’. Step 1704 then identifies the vowel add-ons.

[0190] If the answer in step 1810 is ‘No’, step 1804 will identifies the vowel add-ons.

[0191] The flow charts of A7 to Z7 shortcuts of the 2^(nd) kind and the flow charts of A8 to Z8 shortcuts of the 2^(nd) kind differ in their content only. They are identical in structure.

[0192] The L key was choosen as the starting point for the special signes, because barely a frequent word starts with the letter L.

[0193]FIG. 19 shows a flow chart to determine the double tap short cuts. This section of the program starts with step 1901. In step 1901 a double tap was actuated on the vowel key and a tap on any of the keys.

[0194] Control signs generated in the entry module are read and processed by the processing module. Processing of control signs is started when a control sign is received from the entry module (step 1901).

[0195] Next step, 1902, carries out verification whether the control sign is ‘A’. If ‘Yes’, step 1903 will identify the A double tap shortcuts.

[0196] Step 1404 then identifies the vowel add-ons as described in flow chart, FIG. 21. The procedure then ends by ‘Return’ (step 1405), whereupon continuation is from ‘Start’.

[0197] If the answer in step 1902 is ‘No’, step 1405 carries out verification whether the control sign is ‘B’. If ‘Yes’, step 1906 will identify the B double tap shortcuts.

[0198] Step 1404 then again identifies the vowel add-ons.

[0199] Checking for control signs ‘C’ to ‘W’ is carried out in analogous fashion whereby the respective double tap shortcuts are identified followed by vowel add-ons (step 1404).

[0200] Step 1907 will carry out a verification, whether the control sign is ‘W’.

[0201] If the answer is ‘Yes’, step 1908 will identify the W double tap as described in flow chart, FIG. 20 with the M double tap shortcuts.

[0202] Step 1904 then identifies the vowel add-ons.

[0203] If the answer in step 1907 is ‘No’, step 1909 will carry out a verification, whether the control sign is ‘X’.

[0204] Step 1404 then again identifies the vowel add-ons.

[0205] If the answer in step 1909 is ‘No’, step 1911 will identify the Z double tap shortcuts. Step 1404 then again identifies the vowel add-ons.

[0206]FIG. 20 shows a flow chart to determine the double tap short cuts. This section of the program starts with step 2001. In step 2001 control sign ‘M’ was identified.

[0207] Control signs generated in the entry module are read and processed by the processing module. Processing of control signs is started when a control sign is received from the entry module (step 1901).

[0208] Next step, 2002, carries out verification whether the control sign is ‘0’. If ‘Yes’ the word ‘may_’ followed by a space will be generated.

[0209] Step 2004 then identifies the vowel add-ons as described in flow chart, FIG. 21.

[0210] If the answer in step 2002 is ‘No’, step 2005 carries out verification whether the control sign is ‘1’.

[0211] If ‘Yes’, step 2006 will generate the word ‘make_’.

[0212] Step 2004 then again identifies the vowel add-ons.

[0213] Checking for control signs ‘2’ to ‘8’ is carried out in analogous fashion whereby the respective words will be generated followed by vowel add-ons (step 1404).

[0214] Step 2007 will carry out a verification, whether the control sign is ‘8’.

[0215] If the answer is ‘Yes’, step 2008 will generate the word ‘made^(—)’ followed by a space. Step 2004 then identifies the vowel add-ons.

[0216] If the answer in step 2007 is ‘No’, step 2009 will generate the word ‘market^(—)’ Step 2004 then again identifies the vowel add-ons.

[0217]FIG. 21 shows a flow chart to determine the vowel add-ons. In this section of the program the control signs are determined, which generate vowels, the space and special functions. The control signs 7 and 8 cause a special function, which causes the word generated to be replaced by the same word in bold typeface followed by a space, or by the same word as a title in somewhat larger type and in bold typeface followed by a space. A program loop allows all sequential combinations of the vowels and functions. A control sign is read right before step 2101 (not shown).

[0218] Step 2101, carries out verification whether the control sign is ‘1’. If ‘Yes’, a control sign is read (not shown). Step 2102 carries out verification whether the control sign is ‘7’. If the answer is ‘Yes’, step 2103 will generate the letter sequence ‘al’.

[0219] Step 2104 then carries out verification whether the control sign is ‘6’. If ‘Yes’, step 2105 carries out the function ‘SPACE’, whereupon the program segment ends with ‘Return’ (step 2106).

[0220] If the answer in step 2104 was ‘No’, step 2107 will verify whether control sign ‘7’ had been identified. If ‘Yes’, the just written, or generated, word is replaced by the same word in bold letters (step 2108), whereupon the program segment ends by ‘Return’ (step 2106).

[0221] If the answer in step 2107 was ‘No’, step 2109 will verify whether control sign ‘8’ had been identified. If ‘Yes’, the just written, or generated, word is replaced by the same word as a title in somewhat larger type and in bold letters (step 2110), whereupon the program segment ends by ‘Return’ (step 2106).

[0222] If the answer in step 2109 was ‘No’, step 2111 will verify whether the control sign is ‘0’ (pen is lifted up). If ‘Yes’, the program segment ends by ‘Return’ (step 2106).

[0223] If the answer in step 2111 was ‘No’, the program loop is closed by reading another control sign and executing step 2101.

[0224] If the answer in step 2102 was ‘No’, step 2112 will verify whether control sign ‘8’ had been identified. If ‘Yes’, letter sequence ‘ar’ is generated (step 2113); continuation will be by step 2104.

[0225] Checking for control signs ‘2’ to ‘5’ is carried out in analogous fashion whereby the respective words and letter sequences will be generated followed by step 2104.

[0226] If the answer in step 2114 was ‘No’, continuation is in step 2104.

Advantages of the Present Invention

[0227] Due to application of eight stroke directions, Tap and Double Tap eliminates the need of keys for vowels, j, y, space, punctuation symbols and numerals. Only 40 to 50% of the keys of a QWERTY keyboard are needed and represented, making the key section very clear (small search zone), and only very short distances need to be travelled by the pen. Vowels and space make up 50% of the keying actions. By remembering the six stroke directions, the user will save key searching and travelling distance to the desired key in all these cases.

[0228] Vowel connections have a high incidence in languages. The high speed writing method enables chaining of the various directions in which the pen can be moved, without lifting it off from the entry surface. Entering combinations such as, e.g., ‘ou’, ‘ea’ or ‘ee’ is thus very fast and simple.

[0229] The seven consonants in the immediate neighbourhood of the central T key, including consonant T itself (key section specific to the English language), make up 76% of the consonant keys used, from the standpoint of frequency of use. More than three quarters of all keying operations occur, thus, in this core zone.

[0230] It follows that this combination of key strokes with the simplest chainable ‘writing signs’ (Strokes, Taps ,and Double Taps) features amazing advantages.

[0231] This on-screen keyboard is especially suited for small monitors (watches, mobile phones, SMS, WAP. It requires only five percent of the area of a QWERTY keyboard (for ten-fingers application) which entails great weight savings.

[0232] The present invention has the advantage over all other known text entering systems and can take their place. The future user does not need to know about and change between ‘Graffiti’-alphabet, SMS entry or the touch system.

[0233] Assignment of the eight stroke directions is very easy to remember. The straight down direction represents the I, since I is also written from top down. The vowels are arranged clockwise in alphabetical order. They are all situated on and below the horizontal axis. The three stroke directions located above are reserved for other functions. Umlauts in the German version, e.g. are characterized by a stroke ‘up’, since the dots are also arranged above A, O, or U. Accents in other languages are similarly placed (ã, é, or ô). The method is also adaptable in other respects to all languages with a sound-alphabet, including japanese.

[0234] The hand rest area is located at the same level as the monitor, favoring relaxed positioning. Due to comfortable hand position the pen can be guided precisely by movement of the fingers alone. The hand itself does not need to be guided as is the case for longhand (handwriting) and shorthand (e.g. per Stolze/Schrey), thus needing less space (the arm does not move) and rendering the writing process more elegant. Furthermore, writing in standing position does not present a problem, opening up new applications, e.g. for media reporters.

[0235] At comparable practice effort the method will afford significantly higher writing speed than the QWERTY-keyboard.

[0236] The familiar type-face remains unchanged, taking into account capital/lower case writing and complete, correct spelling. No new, shortened and incorrect type-face needs to be memorized as is the case for shorthand. Nor does the written text need to be deciphered at great effort but has been electronically acquired and is apt for further use. Selection of words from a list is never required during the writing process. This enables the user to concentrate his attention on the entry pad alone.

[0237] Shortcuts and double tap shortcuts enable abbreviated entry of entire words. A set of the one hundred most frequent words is readily available on call. These hundred words constitute 50% of the written language; the 50 most frequent words even make up 45%.

[0238] The presentation of these words by menu windows (e.g. nine-square window) and simple assignment of word location matching the stroke directions result in surprising acceleration of the writing process and of learning advances.

[0239] Many vacant spots still are available for individual words supporting a matching, easy to memorize shortcut or double tap shortcut. Even if the user is familiar with basic functions only, the high speed writing device will soon benefit him substantially.

[0240] A tap executed on the Q key generates the letter ‘q’ followed by letter ‘u’ since q is always followed by u in the English language.

[0241] The simple sign set warrants a virtually 100% recognition rate of the entry. Rather imprecise identification trials by statistical means, referring to a large size vocabulary, are, therefore, not required, resulting in little memory space needed. The simple structure of the short program results in undelayed display of the text entered.

[0242] In contrast with programs based on “artificial intelligence” or on “self-learning ability” direct, undisturbed entry of names, addresses, expert vocabulary, and poetry is easy and accurate.

[0243] The present invention has been developed with user-friendliness in all aspects as the central motivation.

[0244] With the present invention existing models can be upgraded without requiring new hardware components—having todays supply problems—novel devices can be launched.
